3. You got called to put in an epidural for labor analgesia at 0430. The insertion of the needle was uncomplicated. You gave a bolus of 0.75% lidocaine with 2.5 ug/ml of epinephrine. The patient got excellent pain relief from the bolus and you threaded the catheter in easily. As you are taping the catheter in place, frank blood appears in the catheter.
